Latest SVN build is about twice as slow running queries when compared to Java Lucene
------------------------------------------------------------------------------------

                 Key: LUCENENET-192
                 URL: https://issues.apache.org/jira/browse/LUCENENET-192
             Project: Lucene.Net
          Issue Type: Improvement
         Environment: Visual Studio 2008 with .NET framework 3.5
            Reporter: Jeff Johnson
            Priority: Minor


I have been using the java luke tool for comparing query times with java vs C# and the java
query time is consistantly about twice as fast as the C# query time. The index I am testing
was built in C# and contains 10 million documents. I have made sure to "warm up" the index
by running the same query a few times before timing it again.

One example: Querying for a term that exists in every document takes about 1.3 seconds in
C# and 0.6 seconds in java. The total size of my index directory is about 1 GB.
